Hi EveryoneI'm really desperate for help please as even after calling a few technicians I can't find the answer :(

I have a Technicolor TG582n modem and I want to connect an analog phone to it,

Trying to use a Linksys Pap2t to connect Voip (Either 2Talk or Sonetel)

Unfortunately I just get one way sound. And I'm told that I need to open voip on this modem or something. I tried port forwarding the ports, and using telnet to activate voip, but I'm not sure if I did it right. I still get one way sound, meaning I can't hear the person I'm calling.

Thing is, When I used a friends DSL G604t modem, it worked no issues. So I'm not sure if this modem has an issue, or if anyone has done it before successfully? Or can anyone recommend an affordable modem I could probably pick up on TradeMe that works smoothly with the Pap2T ? Thank you so so so much and I appreciate it.

I'm hoping to use Sonetel as thats my usual provider, but. I think it's a port forwarding or issue with the modem. Since it works fine with the friend's DSL G604tI think disabling SIP ALG worked yesterday, I can't remember if I did it on 5060 or 6070 , but now it won't work anymore:

Bless anyone and everyone who is able to help . I am truly grateful. Thank you

Chorus has spent $1.4 billion on making their xDSL broadband network faster. If your still stuck on ADSL or VDSL, why not spend from $150 on a master filter install to make sure you are getting the most out of your connection?I install - Naked DSL, DSL Master Splitters, VoIP, data cabling and general computer support for home and small business.Rural Broadband RBI installer for Ultimate Broadband and Full Flavour

We've always had problems with Technicolour routers and ATAs. The PAP2T has major problems with Thomson / Technicolour or TP-Link devices and we've never got one working correctly, and even if we do, it seems quite temperamental. I suggest you either go out and get an SPA122 or get a new router (new router would definitely be a better option however!)

Those Technicolor's are crap, among other issues by default they do symmetric NAT which breaks voip and gaming because it prevents STUN, UDP hole punching and other "getting around NAT" methods from working.

chevrolux: Check if there is anything called 'SIP ALG' or something similar.

Otherwise you could try registering on 50600 rather than 5060. Or even use TLS on 5061 instead.

1. Changing your SIP port will achieve nothing in this case. Clearly your SIP is working else you would not even be able to make the call. What you are experiencing is an RTP (audio) issue.

2. I'd strongly advise against using TLS while trying to fix another problem. Faulty TLS implementations are common. You'd be likely adding another issue to the problem. At best it will do nothing as it's irrelevant. TLS encrypts the SIP (Call information data), not audio data. What you have is an audio issue.

coffeebaron: Ditch that horrible router and use a Draytek.

I personally use Cisco but Draytek is a far better option for a non techo.

sbiddle: You should never under any circumstances create a port forward for port 5060 on any router. The exception to that rule is if you can explain to me why it's needed..

+1 to sbiddle

Presuming the router supports PNP this should not be needed. I have never needed a port forward for SIP/RTP VoIP use.

Hi All. I'll be trying these shortly on the TG582n. Thank you very much.

I am temporarily using an old DSL-G604T D-Link router which works no issues, but i noticed on Speedtest.net the wireless is 30% less for the download on this modem. In the meantime , could anyone suggest a faster modem that seems to work happily with PAP2T? Probably something I could pick up second hand < $50 would be fantastic. Thank you so much :)

Yes :) You are right. I'm wondering if there is any modem I could pick up inexpensively maybe a Netgear , TP Link or belkin . If anyone knows a model they tried with PAP2T no issues. Don't have a lot to spend. I Thank you very much :)
